Phil, as we look at commercial aerospace, I mean there -- we see really a build challenge across both of the major customers, both Airbus and Boeing. I mean, if you look at some of the data, for example, that we track for build rates. If you go back to Q1 of last year, the build rate combined was around 250, 260 planes. This Q1, it was around 225. If you look at Q4, Q4 build rate on a combined basis was over 350. So the number is probably around 370, I think, for build rate. So substantial decrease here in Q1 across actually both. There's a number of supply chain issues that, frankly, Airbus has talked about very openly that they are facing, so more of a supply chain issue on the Airbus side. And of course, we know the challenges that Boeing is facing not only in the 737 MAX, but I think in general, I would say that they have really, really looked at their production processes to ensure that quality is at the forefront and are really taking steps, I think, to adjust their build schedule as necessary. So significant down in the Q1 for commercial aerospace, which I would say is more than what we had anticipated.
And then as we think about the recovery for the rest of the year, I would expect that the build rates are going to improve. But certainly, those build rates are not going to get to that -- at least we don't think that they're going to get to the levels that they were over the last year or so. So I do expect commercial aerospace in general, to be challenged. This is absolutely not a share issue at all. As you know, we have been gaining content across both -- multiple materials and products that we have on both single-aisle and widebody planes. So our content growth is there. Our share is there. We just need these 2 mega companies to increase their build rates as we go forward. So we'll just -- we'll monitor the situation, but we do see this as a caution for the full year.
